The Pedestrian Who 'Knows the Yard'
You are working a busy container yard with a single access lane between two rows of stacked containers. The lane is 7 m wide; your reach stacker is 4.1 m wide with the spreader retracted and you need to swing the boom to place containers into the second row, which means the rear of the machine sweeps toward the access lane. Pedestrians - including truck drivers collecting paperwork and two yard staff - regularly walk down the lane because it is the shortest route to the site office. There is a marked pedestrian walkway on the far side of the stacks, but it adds about 120 m to the walk. A driver has just walked behind your machine while you were reversing. There is no spotter assigned and no barriers in place.
1. Assess the risk in this setup and identify the controls you would put in place before continuing.

The hazard: The machine's rear and boom sweep into a lane used as a pedestrian thoroughfare. A reach stacker has large blind spots, especially to the rear and to the side opposite the operator's cab, and the swing of the boom and container is not visible to someone walking behind. The lane is 7 m wide and the machine is 4.1 m wide - there is not enough clearance for a person to pass safely while the machine is manoeuvring, and the sweep of the rear extends further still.
Why 'they know the yard' is not a control: Familiarity breeds complacency. The driver who walked behind the machine did so because the route is convenient, not because it is safe.
Controls, in order:
- Separate the hazard - physically barricade the access lane while the machine is working, and route pedestrians to the marked walkway. If the 120 m detour is a problem, that is a management issue to solve, not a reason to leave the lane open.
- Assign a spotter for reversing and for blind-side placement, with agreed signals and a clear position out of the sweep path.
- Define the exclusion zone around the machine's full swing radius, marked and enforced.
- Traffic management plan - one-way flow, speed limits, mirrors/convex mirrors at blind corners, and a designated pedestrian crossing point.
- Communication - radio or agreed hand signals, and a briefing to drivers and yard staff on the changed route.
- Do not reverse without a spotter where the rear is blind and pedestrians may be present.
2. The yard manager objects that closing the lane will slow truck turnaround. How do you frame the response, and what would you do if overruled?
Read the worked answer
Frame it as a consequence, not a preference. A pedestrian struck by a reversing reach stacker is a fatal or permanently disabling event. The cost of a 120 m detour or a slower turnaround is trivial against that, and the legal duty to separate pedestrians from mobile plant is not balanced against convenience.
Offer practical options rather than a flat no:
- Restrict the lane to pedestrians only when the machine is not working in that row, with a formal permit or 'machine working' sign and barrier.
- Re-route paperwork collection to the far side of the stacks so drivers do not need the lane.
- Schedule machine work in that row outside peak truck arrival times.
- Provide a barrier and a spotter as a minimum if the lane must stay open.
If overruled: I would not operate in a way that puts pedestrians in the sweep path. I would stop, record the instruction and my objection in writing, and escalate to the site safety contact. If the barrier is removed while I am working, I stop work until the exclusion zone is restored.
